Mauricio Antunes - Assistant Professor

Mauricio Antunes photoMauricio Antunes, Ph.D. received his B.S. degree in Agronomy and M.S. degree in Crop Sciences from the Universidade Federal de Viçosa in Brazil. He then moved to West Lafayette, Indiana, where he earned a Ph.D. degree in Plant Molecular Biology at Purdue University, under the supervision of Nick Carpita and Tom Hodges. After completing his doctoral degree, Antunes joined June Medford's group at Colorado State University as a postdoctoral fellow, where he was involved in pioneering work in plant synthetic biology to rationally engineer plants to function as sensitive and specific sensors of substances of interest to humans. After spending one year working in Maureen McCann's lab at the Center for Direct Catalytic Conversion of Biomass to Biofuels (C3Bio) at Purdue University, Antunes returned to Colorado State University in 2010 as a Research Assistant Professor in the Biology Department. In 2018, Dr. Antunes joined the Department of Biological Sciences and the BioDiscovery Institute at UNT.

Savio de Siqueira Ferreira started his academic career working with plant viruses (Geminivirideae family) at Universidade Federal de Viçosa - UFV (Brazil), where he received his Bachelor's and Master's degrees in Biochemistry (2006 and 2008). In 2009, he changed field of study to work with sugarcane transcriptome, during his PhD in Biochemistry at Universidade de São Paulo (Brazil), with special interest in genes related to secondary cell wall metabolism and transcription factors regulatory networks. After receiving his Doctoral degree (2013) he started a post-doctoral fellow at the same lab (2014-2015), studying transcription factors, promoter characterization and helping in the sugarcane genome effort, with a brief period (5 months) as a visiting post-doc at The Ohio State University. After a short time back to UFV (2016) studying the transcriptome (RNA-seq) of coffee-rust fungus, he started to work as a post-doctoral fellow (2017-2019) at the LigninLab (Universidade de São Paulo) to work with phenylpropanoid metabolism and lignification in grasses. In January 2020 he joined Antunes Lab to develop studies in synthetic biology, aiming to design genetic circuits to modulate phenylpropanoid metabolism in plants.

Jordan LaChance received her B.S. in Biology from the University of North Texas in May 2021. Here, she worked on and presented research highlighting the biochemical networks of fatty acid biosynthesis in developing embryos of Physaria fendleri, a promising alternative oilseed crop. She then was accepted into UNT's PhD program for Biochemistry and Molecular Biology in August 2021. Currently, Jordan is conducting research to expand understanding of Physaria fendleri metabolism and validate molecular tools to engineer genetic improvements in the species for industrial applications.

Md Shoyeb completed his BSc and MS degree in Genetic Engineering and Biotechnology from Jashore University of Science and Technology, Bangladesh. He received the Vice Chancellor award for his outstanding result and joined as a faculty member in the same department in 2018. He started as a PhD student in UNT's Biochemistry and Molecular Biology Graduate Program from Fall'22. Now, Shoyeb is working to determine whether the long-distance mobility of miRNA via the plant phloem is determined by the location of expression or not. He loves to travel and read historical fiction.

Jesseca Hemminger - Graduate student

Jesseca received her Bachelor of Science in Molecular Biology from Texas Lutheran University in May of 2022. In her time there, she worked on an individual research project that focused on the role of secondary metabolites inhibiting DNA extraction and sequencing samples of Coffea arabica and Coffea canephora. She began UNT's Biochemistry and Molecular Biology Graduate program in January 2023 and is working towards her PhD. Her hobbies include crafting and listening to Taylor Swift.
